Unwanted disruptionThe Anker Stone survived two Wold Wars without severe damage, but in 1963 the German Democratic Republic Government stops the stone production. The company “People•owned enterprise Anker Stone Building Set System“ is closed and manufacturing plants are given away. With the exception of a very few complete Building Sets all the Stones are handed over for free. Everybody can take as much as he or she can carry. According to estimates about 5 billion Anker Stones were sold in four hundred different sets from 1880 to 1963.
